I’ll let you Google the names of the different apps.
I would say, like many others, Remmina.
Putty also has a Linux version, so you can use that as well. Its session management is a bit clunky, but it works and it offers some fairly good functionalities.
But ssh is first and foremost a command line tool. As others have said, invest some time to learn its commands and configuration files.
